The plano-convex lens can converge the collimated beam on the back focus, and can also turn the point light source into a collimated beam. Plano-convex lenses produced by Jiite usually use K.
Plano-convex lenses can converge collimated beams on the back focus, or turn point sources into collimated beams. The lenses are usually made of K9 glass and are coated for wavelengths in the 400-700 nm range. UV quartz is also used as the base material, when UV quartz is used as the base material, it has good transmission in the UV region and a low coefficient of thermal expansion, and can be coated with UV AR film for special cases.
